服务器评测
在Mac OSX 10.10系统上编译了下OpenJDK9，以下仅是个人安装记录，供参考。
编译时间：2015-06-13
系统版本：Mac OS X Yosemite 10.10.4
编译OpenJDK版本：JDK 9
相关软件版本：
- XCode版本：XCode6-Beat4 Version 6.0 (6A267n)
- JDK版本：1.8.0_45
- 软件管理工具：brew
- Xquartz(X11)：2.7.7

OpenJDK官网操作系统等要求
编译前期准备：
•大致了解官网系统要求：
https://wiki.openjdk.java.net/display/Build/Supported+Build+Platforms
•源码下载工具安装（此处采用Mercurial工具[OpenJDK的版本管控工具]从官网下载）：
安装参考资料：
http://openjdk.java.net/guide/repositories.html
https://mercurial.selenic.com/wiki/Download#Mac_OS_X
本机安装脚本：
安装：
$ brew install mercurial
若link失败，则：
$ sudo brew link mercurial
验证版本不低于2.6.3：hg version
安装后版本3.0.2，改为官网下载安装3.4.1了
•安装ccache提高编译速度
$ brew search ccache
$ brew install ccache
•安装freetype（编译时需要）：
brew install freetype
安装失败，提示依赖的libpng无法下载。手工安装：
下载libpng最新版1.6.17(http://sourceforge.net/projects/libpng/files/)并解压：
$ pwd
$ cd ./libpng-1.6.17
$ ./configure –prefix=/usr/local/libpng-1.6.17
$ make
$ make install
$ cd /usr/local/
$ ln -s libpng-1.6.17 /usr/local/libpng
$ brew install freetype
•获取JDK源码：
$ mkdir OpenJDK9;cd OpenJDK9
$ hg clone
$ cd dev
$ chmod u+x get_source.sh
$ ./get_source.sh
编译配置：
$ bash ./configure –help=short
$ bash ./configure –enable-debug –with-target-bits=64
…

make[2]: *** Waiting for unfinished jobs….
解决办法如下或者替换XCode版本为6.3.2或者5.几的：
//OpenJDK9/jdk9/jdk/src/java.desktop/macosx/native/libosxapp/NSApplicationAWT.m
//387行改成：
if (NSApp != nil) {
//[NSApp setDelegate: applicationDelegate];
[(NSApplication*)NSApp setDelegate: applicationDelegate];
if (applicationDelegate && qad) {
[qad processQueuedEventsWithTargetDelegate: applicationDelegate];
qad = nil;
}
}
重新编译：
$ make clean
$ make
